Specification of Letters Patent. Application filed February 17, 1913.

Patented Aug. 18, 1914:. Serial No. 748,838.

To all whom it may concern:

Be it known that I, WILLIAM E. Sonirrs, a citizen of the United Statesof America, residing at Detroit, in the county of lVayne and State ofMichigan, have invented ceruseful Improvements in Stoves,

following is a specification, reference being had therein to theaccompanying drawings.

his invention relates to a stove which is heated by the exhaust of aninternal combustion motor and serves not only for use as a cooker orheater but also as a means for jacketing the mufller to prevent theescape of heat when the muffler is in confined quarters, as for example,a compartment in the hull of a small. boat.

The invention consists in the matters hereinafter set forth and pointedout in the appended claim.

In the drawings, Figure 1 is a view in vertical section of one form ofmulller stove that embodies features of the invention; Fig. 2 is a planView thereof; Fig. 3 is a view in vertical section of a modified form ofthe stove; and Fig. 4 is a plan view of the modication.

Referring to the drawings, an upright pipe 1 from the exhaust manifold.of a motor supports a concave or dished mufl'ler base 2 whichscrewthreaded or otherwise cured to the pipe. A baflle olate 3 is heldin spaced relation at an interval above the base 2 as by suitable studs4 or the like. the proximate faces of the base 2 and battle beine'appropriately shaped to give the proper diffusion and direction to theexhaust so as to silence the latter to a considerable extent. A.discharge pipe 5 is screwthreaded into or otherwise suitably secured onthe battle 3 and is provided with a plurality of inlet apertures 6. Adrum 7 that is retained by a flange 8 on the base or other suitablemeans, is concentric with the pipe 5 and is closed by a top 9 that istelescoped over or screwthreaded on a portion of the pipe 5. A. jacket10 of asbestos or like heat insulating ma terial surrounds the drum 7bands 11 being used to form an air space between the jacket and drum andexterior bands 12 or other suitable means retaining the jacket in.place. An oven having a wall 22 of sheet metal or other suitablematerial is mounted on the top 9 so as to form a substantially flushcontinuation of thc mufllcr drum, the wall being attached to the top asby an angle iron 13 and suitable bolts or rivets 14;. Covers 15 for theoven with suitable handles 16 fit closely around the pipe 6 andeffectively close the oven. As shown in Figs. 1 and 2, the pipes 1 and care in alinement and the drum of the mull'le is substantiallycylindrical. Conseql'lently the pipe 5 passes centrally through theoven. If preferred the base 2 may be substantially oval or of otherdesired conformation as indicated in Figs. 3 and 4-. In such instance amufller exhaust pipe 17 is secured in offset relation to the pipe 1 andthe oven wall 18 is correspondingly formed with a one piece cover 1!)that has a slot at one end through which the pipe 17 passes, the slotbeingclosed when the cover is in position, by a suitable slide 20. Ineither construction if it is desired to prevent the escape of heat fromthe mufl'lcr a sheet 21 of insulating material is placed over the top ofthe mulller and in the base of the oven so that the latter merelybecomes a warming chamber. For cooking purposes this sheet of insulatingmaterial is removed. As a result of this construction the heat of theexhaust of an internal combustion motor may be utilized for cooking.

The device is especially useful on motor boats or other places wherespace is limited and the exhaust of a motor is available. The devicetakes up a little more room than the ordinary muffler and has the addedfeature of insulating the heat from the mul'ller to a great degree.

lVhat I claim is The combination with a mufller drum having an exhaustpipe protruding therefrom adjacent a side wall of said drum, of an ovenupon said drum around said exhaust pipe and having a large compartmenttherein at an end opposite said pipe, a cover on said oven around saidexhaust pipe, and a detachable slide carried by said cover and engagingsaid exhaust pipe to permit of said cover being removed.

In testimony whereof I affix my signature in presence of two witnesses.
